SNES: second controller does not work

alightgoesout

I have installed a fresh RetroPie 4.1 from the img on a Raspberry Pi 3 and I'm having trouble with the second controller and the SNES emulator.

Both controller are the same SNES controller knock-off connected via USB. I have checked them with jstest and they both work flawlessly. There is something strange though, they have different names, "usb gamepad" and "USB Gamepad" (the first one has 11 spaces at the end, while the second one has one). In /opt/retropie/configs/all/retroarch-joypads I have two files: usbgamepad.cfg and USBGamepad.cfg.

In the SNES emulator the second controller does not work. If I only plug one controller I can make any work. In the megadrive emulator, both controller work at the same time without any issue.

I have tries a lot of things and I can't find a solution to my problem. Has someone any clue ?

@alightgoesout Have you configured player 2 in the retroarch config located at:
/opt/retropie/configs/all/retroarch.cfg??

I have edited /opt/retropie/configs/snes/retroarch.cfg as indicated here, but it didn't change anything.

Specifically, I have set input_player1_joypad_index = 0 and input_player2_joypad_index = 1.

It could be that retroarch has the wrong device type loaded, that happened to me once:

Run the SNES game. Press SELECT + X on the working controller.

In the menu navigate to Quick Menu -> Controls ->
and make sure that User 1 and User 2 device type is set to SNES Joypad.

@alightgoesout , did you mapped both inputs through Emulation Station?
Go the the Retropie Main Menu and press start on controller 1. Go to configure input, press A on controller 1. Then, say "Yes" pressing A again. Now, press and hold any key on the controller2 and follow instructions. I have solved the same issue before, doing this.

I hope it helps.
